ABSTRACT:
An illuminated retractor provides a handle and a blade, the blade having a forward portion composed of a light transmissive material. The forward portion blade of the extends from handle and is formed suitably for retraction of body tissue adjacent to a body cavity to be illuminated. The handle is manually grippable and houses an electrical power source which powers a lamp mounted in blade. The forward portion of the blade is formed of a light transmissive material in optical communication with the lamp and is formed for the emission of an unfocused and diffused light for general illumination of the cavity. A surface region of the blade body may be frosted or ground so as to widely diffuse light emitted from lamp, thereby illuminating a wide area of a body cavity. A plurality of interchangeable blades of diverse shapes includes a perio-ostial elevator tip and a dental cheek retractor. A blank blade is provided which can easily be customized into a variety of shapes. In another embodiment, the blade has at least one mirrored reflecting surface in combination with frosted diffused light emitting surfaces.
